Title: Frequency adjustment circuit for signal processing filter
Inventor: IIDA AKIHIRO
IPC: H04N5/14
Filed: 1989-04-28
Abstract: PURPOSE:To attain accurate signal processing by correcting a center frequency of a signal processing filter equal to the frequency of a reference clock. CONSTITUTION:An input signal is fed to a phase comparator circuit 29 via a switch 25, a signal processing filter 26 and a switch 27 and the phase is compared with that of a reference clock. Then an output voltage corresponding to a phase difference component is generated from a loop filter 30 and fed to the signal processing filter 26 via an S/H(sample-and-hold) circuit 31 and the center frequency fO of the signal processing filter 26 is controlled to be equal to a frequency fS of the reference clock. Since the center frequency fO is subject to negative feedback control so as to be equal to the reference clock frequency fS, accurate signal processing is applied.

Title: Signal generation circuit
Inventor: SHIRAI TOSHIHITO
IPC: G01R23/15
Filed: 1997-04-28
Abstract: PROBLEM TO BE SOLVED: To detect occurrence of abnormal frequency by checking the frequency of an output signal from a signal generating section for a predetermined normal frequency range including a specified frequency. SOLUTION: When the signal generating section 2 in a frequency monitoring section 3 is normal and an output signal of a specified frequency is generated, the output signal SF from a BPF 11 has a frequency substantially equal to that of an output signal. A DC signal SW from a rectifier circuit 13 has a level higher than the lower limit threshold value VL of a level detector 14 and the output signal ST=1 which means that the frequency of output signal is normal. When time frequency of output signal fluctuates by an amount Δfs or more due to failure of the signal generating section 2, for example, the output signal SF from the BPF 11 attenuates by a specified value or more.  Consequently, the level of the DC signal SW from the rectifier circuit 13 drops below the lower limit threshold value VL, of the level detector 14 and the output signal SI=0 which means that the output signal is abnormal. More specifically, abnormal frequency can be detected by generating an abnormality decision signal of logical value 0 from frequency monitoring section 3 when the frequency deviates from a normal range.

Abstract: PURPOSE:To control the fuel correctly irrespective of coil resistance changes due to an increase of temperature by connecting a current detection resistor to the solenoid coil of an injector in series and by controlling the valve opening work current and the closed valve holding current which flow through the coil based on the detection value. CONSTITUTION:When the voltage drop generated across a detection resistor 25 by the current I of a solenoid coil 1 is decreased down to about 0.15V, an FF10 is set by the output 3 from a comparator 14, turning the control transistor 2 on so that the current supplied by a power supply +B is gradually increased, and when the voltage drop reaches about 0.17V, the FF10 is reset by the output 2 of a comparator 13. Thereby, the transistor 2 is made off, then the current I generated by the back electromotive force of the coil 1 is decreased as it flows through the second short circuit consisting of a transistor 4, and these conditions are repeated in turn and continued until a repetition input signal Ti is reduced to zero. When the signal Ti becomes zero, the ransistors 2, 4 are both made off, thus the passage of the current I for the coil 1 is blocked, and the current I is blocked, and the current I is made zero.
